DEVICE FOR CONTROLLING FROM A DISTANCE THE PASSAGE OF GAS.

Specification of Letters Patent.

Application filed August 19, 1908.

Patented June 4, 1912. Serial No. 449,354.

To all whom it may concern Be it known that we, ALBERT MAURICE AUBERTand JEAN MARCEL AUBERT, citizens of the Republic of France, residing at135 Route de Versailles, Billancourt, Seine, in the said Republic, haveinvented certain new and useful Improvements in Devices for Controllingfrom a Distance the Passage tion.

This invention relates to a device for controlling from a distance thepassage of gas; the said device being operated with aid of threeelectric leads, that is to say, the device comprises two electromagnetswhich are thrown into circuit alternately by turning a suitable switch,one of these magnets determining the admission of gas to the burner andthe other determining the cutting off of this gas.

The device consists essentially of a valve designed to control a gaspassage and arranged in such a manner that it is actuated by a balladapted to engage its lower face, said ball being actuated through theintermediary of a conical surface on a cylindro-conical body ofrevolution, the lateral displacement of the latter in one directionactin to raise the valve from its seat, while the displacement of saidbody in the opposite direction permits the return of the valve to itsseat under the action of a spring.

The accompanying drawing is a vertical section of one form of deviceembodying our invention, the body of revolution being represented as inmotion.

The apparatus comprises a tubular casing a in the upper part of which isscrewed a tube 7) which holds in place the seat 0 of the valve (Z; thelatter is provided with a collar 6 of any suitable form and material, isguided by a tubular extension f and is held on its seat by a spring g. v

Into the respective sides of the casing 41. are screwed caps h and hcontaining bobbins, i, i of solenoids j, j. Within the hollow bobbinsslide the solenoid cores is, is; the two cores are fixed to the oppositefaces of a disk Z having a central conical portion and two cylindricalportions m, m of difierent radii, on its periphery. Accordingly ascurrent is transmitted through solenoid 7' or solenoid j, the disk Z ismoved to the right or to the left. Preferably the coreslc 7c and thedisk Z are bored axially so that air may pass from one end to the otherwhen the disk is displaced under action of one or other of thesolenoids.

Extending co-axially through the seat 0 of the valve is a short tube ain which is lodged a ball a resting on the disk Z. The diameter of thisball is such that when the ball a rests on the cylindrical portion on ofthe disk, the valve 4% can rest upon its I, 7 seat, but when theballrests upon the cylindrical portion on of the disk the valve d isfully opened, while when the ball rests on the conical portion of thedisk as shown in the figure the valve occupies an intermediate position.energized the valve is lifted, while when the solenoid y" is energizedthe valve is able to.

return to its seat under action of spring 9. A simple switch having twopoles suflices to control this valve from a distance. When When thesolenoid is y the valve is open the gas passes through the connection at0 to that at p by way of the orifices 1' in the valve seat 0 and theorifices g in the tubular extension f. Inasmuch as the ball a hasconsiderable play in the tube 0 gas can also pass through this tube; thedirection of the passage of. the gas is shown by the arrows.

It will be seen that the cylindrical parts m m of the disk keep thevalve stable in its open or closed position, so that when it is openvibrations do not cause it to shut. Moreover, the apparatus isexceedingly sensitive since friction is avoided by the use of a ball anda freely movable body of revolution.

The solenoids or electromagnets and their armatures may be of anysuitable form and may be attached to the casing in any suitable manner.

Having thus described the nature of our said invention and the bestmeans we know ofcarrying the same into practical effect, we claim:

1. Mechanism for controlling gas from a distance, comprising a casing,tubes attached thereto for the admission and escape of gas, a cut-offvalve, a spring to press said valve on its seat, a freely and axiallymovable body having a conical surface of revolution between cylindricalsurfaces of dilferent diameters axial therewith, said body maintaineddistant from the walls of the casing to permit'the passage of gas aroundand past the body under all conditions of operation, a round facedmember between said body and valve, and means controlled from a distancefor moving the entire cylindroconical surface in one direction or theother. 2. Mechanism for controlling gas from a distance, comprising acasing, pipes attached thereto for the admission and escape a of gas, acut-off valve, a spring to press the valve on'its seat, a freely andaxially movable member having a conical surface of revolution betweencylindrical portions of different diameters and co-aXial therewith,

" a ball between said member and valve, cylindrical bearings mounted onopposite sides of the cylindro-conical body and co-axial therewith, twoelectro-magnets adapted to be controlled from a distance by a source ofa current, and cores attached to the cylindroconical body movable insaid bearings.

3. Means for controlling the passage of gas'from a distance, comprising'a casing, pipes attached thereto for the admission and 1- escape ofgas, a cut-off valve, a body of revolution free to move, composed of acentral conical part and two lateral cylindrical parts-of diiferentdiameters, a freely'movable ball interposed between the body ofrevolution and the valve, an electro-magnet on each side of the body,andcores for said magnets mounted on the opposite faces of said body andco-axial therewith.

4. Means for controlling the passage of gas from a distance, comprisinga casing, tubes on the casing for the admission and escape of gas, avalve, a seat for said valve, a freely movable'cylindro-conical body ofrevolution, a ball interposed between said body and the valve, a socketformed on'the tions, and means controlled from a distance to axiallymove said member to causethe ball to open the valve and permit it toclose. In testimony that we claim the foregoing as our invention we havesigned our names in presence of two subscribing witnesses.
